U.S.-Slovak Materials Research on Novel Magnetic Excitations in Low Dimensional Magnetic Systems

盖恩斯维尔佛罗里达大学的Mark Meisel和科希策萨法里克大学的Alexander Feher共同完成了一个美国和斯洛伐克的研究项目，主要研究新型低维无机磁铁的热力学和磁性。研究人员打算在他们最初的理论和实验证据的基础上，指出在高度各向异性的线性链反铁磁材料中存在一类新的磁激发。计划进行中子散射实验来证实这些发现，并合成和表征新型低维磁体的粉末和单晶样品。结果有望有助于我们理解几个低维磁系统的性质，特别是突出在外来超导体（例如，重费米子和高tc铜超导体）中观察到的配对机制。这个凝聚态物理项目实现了推进科学知识的计划目标，使美国和中欧的顶尖专家能够结合互补的人才，并在共同感兴趣和有能力的领域汇集研究资源。?？

INT 9722935 Meisel This U.S.-Slovak research project between Mark Meisel of the University of Florida, Gainesville, and Alexander Feher of the Safarik University, Kosice, will feature the investigation of the thermodynamic and magnetic properties of novel low dimensional inorganic magnets. The researchers intend to build upon their initial theoretical and experimental evidence that points to a new class of magnetic excitations in a highly anisotropic linear chain antiferromagnetic material. Neutron scattering experiments are planned to confirm these findings as well as synthesis and characterization of powder and single crystals samples of the new low dimensional magnets. Results are expected to contribute to our understanding of the properties of several low dimensional magnetic systems, specifically highlighting the pairing mechanisms observed in exotic superconductors (e.g., heavy-fermion and high-Tc cuprate superconductors.) This project in condensed matter physics fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Central Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ??
